Definitions

  • the present invention concerns a system for locating a sensor so as to make it possible to obtain different positions at the time of installation on an automobile, depending on the parameters sought.
  • a difficulty arises if one wishes to mount the same sensor on an entire line of vehicles because of the fact that certain parameters, such as the angle of ignition advance, vary from one type of vehicle to the next.
  • the same difficulty arises on the same type of vehicle if one wishes, without changing the sensor, to modify the ignition advance either as a function of changes in the characteristics of the motor during its life or in order to take into account temporary or local changes in the composition of fuels, especially if the protection against knocking of the engine under consideration is slight for the given advance or, finally, to permit conformity to different standards such as those for pollution control.
  • the present invention makes it possible to reduce these difficulties by sliding the sensor on a fixed bar and immobilizing the sensor on the bar either during manufacture or at the time of installation on the vehicle.
  • This bar is most frequently in the shape of the arc of a circle whose center coincides with the center of the disk made unitary with the crankshaft and bearing on its periphery the irregularities which influence the characteristics of the sensor when they pass in front of it.
  • the sensor is fastened, either by a mechanical device such as protuberances or cotter pins or by the permanent bonding of the attachment bar, at a predetermined position along the length of the said bar, before mounting on a vehicle of a given type.
  • FIG. 1 represents a frontal view of a sensor and attachment bar according to the invention, and a disk made unitary with the crankshaft;
  • FIG. 2 represents a view, from below, of the same unit.
  • a sensor 1 of a known type electromagnetic for example, generates electrical signals based on the detection of the irregularities 2 or 3 or 4, etc. on disk 5. It therefore transmits information on the velocity or angular position of the crankshaft to a computer in an associated electronic unit.
  • This sensor 1 is mounted so as to slide on a bar 6 which is attached, for example by two screws 7 and 8 at its ends, to the clutch bell housing 9.
  • the bar is provided with a certain number of equidistant holes 10, 11, etc. (seven holes, for example), each of which may be used either to adjustably fix the sensor with the help of a small cotter pin 14 or to mould or bond the sensor, with the hole making possible an anchoring of the moulding in question.
  • Each of the holes corresponds, for example, to an initial ignition advance value, a positive value to the right of the axis of symmetry XX' and a negative value to the left. These different values are represented by the angles ⁇ with respect to axis XX' in FIG. 1.
  • the initial ignition advance angle is determined as a function of the type of vehicle involved, either by passing the cotter pin 14 through the appropriate hole in the bar 6 or by the appropriate positioning of the sensor on the bar 6 in the mould or collar of the moulding bonding element.
  • the bell housing 9 features, opposite the disk 5, an oblong opening 13 made during casting, whose dimensions are compatible with the various possible positions of the sensor 1 along the attachment bar 6. As this opening 13 contributes neither to the attachment of the sensor 1 nor to its aiming, it may be left unfinished after casting without requiring additional machining.
  • the seven possible angular position values may vary from -6° to +6° in increments of two degrees. These numerical indications are provided by way of example only and are not in any way to be considered to narrow the scope of the present invention.
  • the sensor unit is made of a plastic material and the attachment bar is made of a material identical to that of the body of the sensor 1, said bar being formed either during a previous moulding operation or during the operation in which the body of the sensor is formed.
  • the mould is provided with a slide portion in the shape of the arc of a circle and bearing the imprint of the bar, making it possible to vary the position of the latter with respect to the body of the sensor.
